This logic is commonly used before determining the euler angles of class sums. Its purpose is to perform a sensitive mass centering of the class sums based on radon transformation. Usage of this algorithm improves common line finding during the consecutive reconstruction process.

| Error | √(xVariance+ yVariance) of the given class sum, based on before and after the performed shifts, so basically 2D standard deviation. If no shifts have been performed, the error will be 0. |
